Abstract

An air cleaner assembly with a restriction indicator (14) includes a housing (12) having an exterior surface around an interior volume. The housing includes a bore (42) extending through a portion of the exterior surface of the housing surrounded by a bore wall (38) protruding from the portion of the exterior surface. A receptacle wall of the housing is disposed around the bore wall and is radially spaced from the bore wall to form a channel (44) between the bore wall and the receptacle wall. A restriction indicator (14) measures a restriction in the interior volume and displays an indication of the restriction. The restriction indicator includes a stem (46) that is at least partially insertable into the bore that engages an inner surface of the bore wall. One or more tabs (52) of the restriction indicator are at least partially insertable in the channel and removably couple to the receptacle wall.
